Mainframe systems programmers are responsible for implementing and maintaining an organization's server computer, as well as performing updates and routine maintenance on the mainframe computer to prevent problems from arising. Troubleshooting may occasionally be necessary in this position to ensure that no security holes exist in the mainframe system, and tests should be carried out regularly to identify any bugs or other problems.
Data must be monitored to ensure it is accessed only by authorized personnel, and the speed of data transmission should also be monitored to ensure that the system operates at an optimal pace. These programmers must test new operating systems and software which are implemented on the mainframe and connecting computers, and they may also provide technical support, guidance, and consulting. Some may be expected to train others and create supporting training documents and manuals, and they must also document all procedures that have been carried out. Diagrams of the infrastructure may need to be created, and it's important that they stay up-to-date with all changes in the field to recommend positive changes to management and implement the best practices.
A bachelors degree in computer science, information technology (IT), or a related field and at least a few years of experience in system programming and administration are generally required for this position.
